Component Design Guides
The initial reviewed component design guides are available for a selected set of automotive and wide-input buck regulators. Each guide explains application fit, external-component choices and thermal/EMI layout priorities. Additional guides remain in preparation; this is application guidance, not a product database or replacement catalog.

LM65625-Q1 Power Supply Design Guide
Application-engineering guide to the LM65625-Q1 synchronous automotive buck converter for compact, EMI-conscious local rails. It explains operating-mode, frequency, passive, thermal and layout decisions and the evidence needed beyond device-level qualification.
View design guidance ↗LM5161-Q1 Power Supply Design Guide
Application-engineering guide to the LM5161-Q1 for high-voltage buck and Fly-Buck use. It explains when its wide-input architecture is relevant, how constant-on-time behavior affects passives and layout, and what must be verified for 24 V or 48 V auxiliary rails.
View design guidance ↗TPS54260-Q1 Power Supply Design Guide
Application-engineering guide to using the TPS54260-Q1 as an automotive step-down regulator. It focuses on supply-envelope definition, external magnetics and capacitors, thermal and EMI layout, protection coordination and evidence required before the device is approved in a design.
View design guidance ↗LM76002-Q1 Power Supply Design Guide
Application-engineering guide to the LM76002-Q1 synchronous step-down regulator for automotive and commercial-vehicle rails. It covers operating-envelope checks, switching-mode choices, passives, thermal paths, EMI layout and system validation.
View design guidance ↗LMR38020-Q1 Power Supply Design Guide
Application-engineering guide to the LMR38020-Q1 for wide-input automotive buck conversion, especially 48 V-class auxiliary rails. It frames voltage-margin, low-noise layout, magnetics, thermal and fault-response decisions without claiming measured performance.
View design guidance ↗LM5012-Q1 Power Supply Design Guide
Application-engineering guide to the LM5012-Q1 high-voltage non-synchronous buck regulator. It focuses on wide-input front ends, external diode and magnetic stresses, constant-on-time behavior, thermal design and EMI validation for 24 V and 48 V-class systems.
